The equation may have memory or delay effects in the coefficients, both with respect to state and control, and the noise can be degenerate.
Avoiding collisions with obstacles is of fundamental importance for the safe navigation of unmanned aerial vehicles (uavs) and mobile robots.

Stochastic control or stochastic optimal control is a sub field of control theory that deals with the existence of uncertainty either in observations or in the noise that drives the evolution of the system. The system designer assumes, in a bayesian probability-driven fashion, that random noise with known probability distribution affects the evolution and observation of the state variables. Stochastic control aims to design the time path of the controlled variables that performs the desired cont.
